NAME¶
mkdep —
construct Makefile dependency
list
SYNOPSIS¶
mkdep |
[-ap]
[-f file]
[flags]
file
[...] |
DESCRIPTION¶
mkdep takes a set of flags for the C compiler and a list of C
source files as arguments and constructs a set of include file dependencies
which are written into the file ``.depend''. An example of its use in a
Makefile might be:
CFLAGS= -O -I../include
SRCS= file1.c file2.c
depend:
mkdep ${CFLAGS} ${SRCS}
where the macro SRCS is the list of C source files and the macro CFLAGS is the
list of flags for the C compiler.
The options are as follows:
- -a
- Append to the output file, so that multiple
mkdep's may be run from a single Makefile.
- -f
file
- Write the include file dependencies to
file, instead of the default ``.depend''.
- -p
- Cause mkdep to produce dependencies of
the form:
so that subsequent makes will produce program directly
from its C module rather than using an intermediate .o
module. This is useful for programs whose source is contained in a single
module.
